To all whom it may cancer 12 I Be it known thetl, *Gnnniins E. Gensrrn, a citizen of the United- Ststes, residing .at Phiiedelp-himin.the county of Philadelphia and State of Pennsyivsnie, have invented newnnd useful improvements in Car Vestibole-Doors: and Traps, of which the following is e specifics-tics.-

' invention relates to cor f 'l f itibule doors end traps, the object oi the invention being to PIOTVIdQ.'8J1 effective device oftln's charecter involving menus for opening the 'vestibuledoor withieese, the said means he ingof suchcharecteres to not interfere in 1 respect with the departure of a. passenger from or his entrance. into the car.

' The invention includes other advantageous features which with the foregoing will be set forth at length in the following description wherein is outlined that form of embodiment of theinvcntion which I hnveselectcd for ill istretion in Y the drawings accompanying and iorming'part of this specification.

To reak the joint between the said trap sections to thereby effect the easy thrust downward by foot or hand As said rod 25 moves downward the upper and long arm of the angle lever 23 is moved in a corresponding direction so as to swing'the other arm of said anglelever to the right in Fig. 1, the angle lever on such movement pulling the bar 28 to the right and moving the lower long branch of the lever 29 in a corresponding direction, the short upper branch of said lever 29 being swung to the eft and the lug or pro-i which lifts the section, 10 of the trap and thereby breaks the joint between said section and the corresponding section 11, so that the opening movement 0 the door can be'starte and-vestibule door 9, being closed, the sec- "opening of the. vestibule door 9, therod 25 is jection 35 thereon serving to lift the lever 34 ,following which the full opening movement. of the door can be easily efiected. Owing to the construction and arrangement of the several levers I initially apply to the said trap a powerful leverage which insure" the ready and easy elevation of the same anc the consequent initial At this point it is an easy matter to fully swing the door 9 open; and as it does 0 en, the sections 10 and 11 are upwardly fo ded and the section 11 will lie against the section 10 in the space between thedoor 9 and car 2 when said door 9 is open.
